Status Assessment of Drinking Water Quality in State and District Hospitals of Tripura
1.0 Introduction :
Water is one of the most important constituents of life support system. It is an essential ingredient of animal and plant life. It is indeed a wonderful chemical medium which has unique properties of dissolving and carrying in suspension a huge varieties of chemicals. Hence it can get contaminated easily. Natural surface water bodies often have impurities from various sources. The impurities may be suspended particles, colloidal materials and may also be dissolved cationic and anionic substances. Various natural and human activities, like industrial, domestic, agricultural activities and others are creating water pollution particularly in surface and ground water system.
The quality of water is of vital concern for mankind since it is directly linked with human welfare. It is a matter of history that faecal pollution of drinking water caused water-borne diseases which wiped out entire population of cities. At present, the menace of water-borne diseases and epidemics still looms large on the horizons of developing countries. Polluted water is the culprit in all such cases. The major sources of water pollution are domestic waste from urban and rural areas, and industrial wastes which are discharged into natural water bodies.
2.0 State Profile :
Tripura is one of the smallest states of North East India. The State of Tripura is situated in the eastern part of India and surrounded by Bangladesh on the West, South and North. Its Northeastern and Eastern boundary is demarcated by Assam and Mizoram respectively. The state lies between 22056’ to 24032’ North latitudes and 91009’ to 92020’ East longitudes with an aerial extent 10,491.69 sq. km.The population of the state as per the 2001 census is about 31,91,168.
The state has four administrative districts namely West Triprua, South Tripura, North Tripura & Dhalai, 15 Sub-Divisions, 40 Blocks and 14 Towns including Nagar Panchayats. Agartala is the state Capital and Udaipur, Kailashahar and Ambassa are the District headquarters.
3.0 Objective :
Impurities in potable water causes health disorders. In the hospitals of Tripura patients generally take the drinking water directly from supplies provided by the Public Health Engineering. If this drinking water becomes contaminated, the patients may suffer from some water born diseases.
The main objective of the present study was to assess the Drinking Water quality of some of the Hospitals of Tripura.
4.0 Methodology :
In order to assess the drinking water quality of different Government Hospitals of the state, a scientific team of Tripura State Pollution Control Board collected the drinking water samples from seven Government Hospitals and analysed different parameters of these in the Laboratory of Tripura State Pollution Control Board.
The Physico-Chemical quality of drinking water was analysed using the standard methods given in APHA (American Public Health Association).
5.0 Study Areas :
For the purpose of drinking water quality monitoring of Hospitals, four State Hospitals and three District Hospitals were selected.
State Hospitals :
i) G. B Pant. Hospital, Agartala.
ii) I.G. M. Hospital, Agartala.
iii) B. R. Ambedkar Hospital, Agartala.
iv) Rajib Gandhi Cancer Hospital, Agartala.
District Hospitals :
v) Kulai District Hospital, Ambassa, Dhalai (Proposed).
